Kevin - I had a very, very rich running condition - clouds of black smoke, carbon dripping from the tailpipe, etc.

Fixing the heat riser fixed about 75% of the problem, and fixing a severely leaking exhaust manifold fixed the last 25%. My machinist took 0.030" out of it to get it flat, and I think the heavy leak was also heating up the intake and essentially acting as a hot box. I think that also led to the carbon I just cleaned out, although apparently those engines could build up carbon anyway (per the service letters). Good luck!

Hope the spring fixes it for you!
